For my particular i5 2500k at least. I could make 50-100 passes of LinX (latest Intel Linpack libraries with AVX) with 90 percent ram usage (6GB out of 8GB). However, I would crash Prime95 26.6 custom 6GB blend after the 8 hour mark even though temps were about 8-10 C lower.

Opinions vary, but the recognized standard is a 12hr blend run with Prime95; LinX (AVX) is an attempt to lower the testing time while achieving the same level of stability.

As you can see, end results don't always exactly match the desired outcome.

Edit - For the sake of clarity: Think about the differences between the two programs, just what each is testing, and how; that may shine some light on your stability issues.Edited by jlells01 - 10/7/11 at 2:46am

P.S. - I'll readily admit to being in agreement regarding sour skittles deliciousness; how do you manage to eat anymore than a few without a layer of your tongue, and the roof of your mouth being decimated?
